- `make run` — Start dev server on port 4000
|
|
- `make repl` — Start nREPL
|
|

## Docker
|
|
|
|
Docker runs alongside local dev on different ports:
|
|
|
|
| Service | Local dev | Docker |
|
|
|----------|----------------|----------------|
|
|
| btcprice | localhost:4000 | localhost:4041 |
|
|
| btcdata | localhost:4100 | localhost:4101 |
|
|
|
|
btcprice's docker-compose includes btcdata via `include: ../btcdata/docker-compose.yml`.
|
|
|
|
## REPL Commands
|
|
|
|
```clojure
|
|
(dev-prep!) ;; Prepare dev system
|
|
(go) ;; Start system
|
|
(reset) ;; Reload code & restart
|
|
(halt) ;; Stop system
|
|
```
|
|
|
|
## Architecture
|
|
|
|
- **Framework:** Kit (Integrant-based)
|
|
- **Server:** Undertow
|
|
- **Routing:** Reitit
|
|
- **Templates:** Hiccup + vanilla JS WebSocket
|
|
- **Styling:** Tailwind CSS v4
|
|
- **Data backend:** btcdata (separate service at BTCDATA_URL, default http://localhost:4100, WebSocket at ws://localhost:4100)
